Abstract

The purpose of this investigation was to determine the impact sensitivity of commercially pure titanium, titanium alloy 6Al-4V, and precipitation hardened 15-7 Mo stainless steel when exposed to liquid nitrogen tetroxide. An explanation is given of the probable mechanism of the limited ignition resulting from impact.Commercially pure titanium and titanium alloy 6Al-4V ignite about 50% of the time when impacted with a 0.5 inch diameter flat striker having an energy of 200 ft-lbs. Storage of the commercially pure titanium in N2O4 decreases the energy needed for 50% ignition to 60-70 ft-lbs. The sensitivity of the alloy is unaffected by storage in N2O4.Precipitation hardened 15-7 Mo stainless steel was not impact sensitive in liquid N2O4.
